' 5 claims. (ci. 12o- 42) This invention relates to a fountain pen and it aims to provide a relatively inexpensive, durable and compact construction which combines four fountain pens in one, yet, maintaining the j barrel and pen points of normal size, and affording a considerable amountof ink for each point. The invention enables four different colors of ink 'to be used or `fourrseparate supplies of ink even of the same color, with four different styles l, of pen points.

It further aims to provide a construction which will eliminate any mechanical appliance which must be operated incidental to the shifting from one color or pen point to another color or pen point, and also without interfering with liuent writing. It is further aimed to provide a construction which eliminates any mechanical device necessary for the vfilling of the ink sackets or bladders, ',-thus dispensing with the usual levers, -wire rings,

locking pins, rivets, pressure bars andthe like. IThe more specic Objects and advantages will in part be pointed out hereinafter and otherwise become apparent from a consideration of the description following taken in connection with ac-v companying drawing, illustrating an operative embodiment.

In said drawingzy Figure 1 is a view of the pen primarily in elejvation, the end caps being shown in central longitudinal section to disclose details;

' Figure 2 is an elevation of the fountain-pen with the caps removed, and one section disposed at an angle tothe other as is done when filling;

Figure 5 is a cross sectional view takenl on the Yline 5-5 of Figure`4.

tions A which is selectively engageable in re.

cesses 13 and 14 of the other section, in writing or closed position, 'and in the filling position of Figure 3 is a central longitudinal sectional Figure 2, respectively. As one section A is turned respectively to the other section, the sections yield ,automatically since an expansive spring 15 surrounds the bolt l1 between its head 16 and the adjacent section as best shown in Figure 3. The sections thus have a snap action when the4 lug '12 engages the notches or recesses 13 and 14.

The ends of sections A are recessed or hollow as at 17 to provide barrels in which ink sacks or bladders 18 are disposed. Said barrels or recesses l'l are open in theaforesaid plane 10 and to aid in retaining and supporting the bladders 18, marginal anges 19 are provided on the sections in said plane 10, such flanges preferably being wider at the inner vends 20 than at the sides. The bladders 18 thus being exposed, are engageable by the fingers or an instrument to expel air to facilitate filling. Said bladders are preferablyI of the usual rubber construction and telescopically grip the exterior of tubes 21 of the barrel which are integral with a transverse wall 22 and communicate with end sleeves 23, which are semicircular in cross section, like the remainder of the sections.

, Suitable pen points 24 are removably disposed in the sleeves -23, and held friction tight 4by means of removable feeder bars 25 also extending into 'said sleeves. Said feeders 25 have channels 26' to convey the ink from the sacks 18, through the tubes 2l, apertures in the wall 22 to the opening in the split pen point.

As a result o f theconstruction described, when it is desired `to iill either of the bladders 18, the

pen sections are swung from normal position, in which they are held through the interengagement of the lugs 12 and notch 13, into the position of Figure 2 where they are so held through the-interengagement of the lugs 12 and recess 14, In thisposition, any of the pens may be disposed' within a supply of ink following expulsion of air from the bladder by engagement of the finger or instrument therewith through Ithe open side-of the barrel inthe. plane 10. When the pen is filled, the writer may use either of the points.

1. A fountain pen having two sections-means pivotally mounting and normally holding said sections in alinement, each section having i a fountain pen unit including a barrel, and Vthe .barrels being each provided with an openingin the portion facing the other barrel, which openings are closed when the barrels are in alinement.

2. A fountain pen having two sections, means pivotally mounting and normally holding said sections in alinement, each section having a fountain pen unit including a barrel, and the barrels beingA each provided with an opening in the portion facing the other barrel, which' openings are closed when the barrels are in alinement, said means comprising a bolt, interengag'ing recesses, and a lug on said sections to hold the s'ections in normal position and in angular positions, and spring means associated with the bolt-nor- -.mally maintaining the lugin engag'ement'with one of the recesses.

^ 3. A fountain pen having two sections,-means pivotally mounting. and normally holding. said sections in alinement, .each section having a fountain pen unit including a barrel, and the barrels being each provided with an opening in the portion facing the other barrel, whlchopenings are closed when thebarrels are in alinement, each fountain pen unit having a transverse wall, a nipple on the inner side of said wall, and a tube on theouter side of said wall, a bladder engaging said nipple a'nd manually engageable through Saidopening for` relling, and a fountain pen point and feeder engaged in the tube.

'^ 4; A fountain pen construction comprising two sections pivotally secured' together intermediate of their en'ds, each \section having acomplete fountain pen at each end thereof, means normally securing the sections in 'alinement and per- 'mitting angular displacement thereof for individual filling of the fountain pen,`and each of i said barrels having an opening thereinnn the portion facing another barrel, which openings are closed when the barrels are inalinement.

v5. A fountain 'pen construction of the class described havingtwo sections, means pivotally\. connecting the sections together intermediate of their ends, a point and feeder bar at each end of each section and a barrel cooperating therewith,

an individual ink supply means for each feeder' bar and point mounted in each barrel, and each of said barrels having an opening therein in the portion facing another barrel, which openings are closed when the barrels are in alinement.
